ROLLING WINDOW-SCREEN.

specification.

My invention relates to rolling window screens wherein a suitable screen is secured a to a roller having a pinion thereon and may be operated by raising or lowering the lower sash or may be operated independently of the sash, and the objects of my invention. are first, to provide improvedmeans for operating a rolling window screen which may be automatically operated when the lower sash is raised or lowered second, to provide improved means for disconnecting the screen from the operating means; third, to provide means for operating the screen independently of the window by means of a rack which engages a pinion on the roller; fourth, to provide suitable guideways for the screen and the rack; and fifth, to provide means for connecting or disconnecting the lower end of the screen from the window sill.

I accomplish these several features by means of the device disclosed in the drawings forming a part of the present specification, wherein l1ke characters of reference designate similar parts throughout the said specification and drawings and in which- Figure l is an elevation of a window disclosing my invention secured thereto. Fig. 2 is a vertical sectional view of Fig. 1 disclosing the roller secured to the lower end of the lower sash. Fig. 3 is an enlarged detailed sectional view disclosing the manner in which the screen. roller is rotatably secured to the lower end of the lower sash, the manner in which the pinion on the roller is engaged by a stationary rack secured to one side of the window frame, and the means whereby the said pinion is moved from engagement with the said rack. Fig. 4: is a view similar to Fig. 3 but disclosing the pinion removed from engagement with the rack. Fig. 5 is a broken plan view of Fig. 3, disclosing the screen retaining stripssecured to the sides of the window frame, the stationary rac and the pinion on the screen roller in engagement therewith.

in which the upper edge of the said screen is secured to the roller and the lower edge to a relnforclng strip adapted to be secured to the window sill. Fig. 7 is a broken sectional v ew through the upper and lower sashes, disclosing a modified form of the invention wherein the roller is stationary and rotatably mounted on the window frame while the rack is slidabl mounted within the retaining strips of t e screen and adapted to rotate the roller and wind 11 the screen independently of either sash. ig. 8 is a plan view of the roller inengagement with the slidable rack, disclosing the relative positions of the screen retaining strips, the screen having been removed. Fig. 9 is a plan view of the securing strip at the bottom of the screen disclosing the movable rack secured thereto, the manner in which the rack is slidably mounted within one of the screen retaining strips, and the manner in which the screen is engaged by the retaming strips.

Referring to the drawings, the numeral 1 is used to designatethe lower end of the lower sash of a window having the brackets -wh1ch one end of a roller 4, having a longitudinal slot 4:, and the pinion 5, is rotatably mounted. The pinion 5 is. arranged to mesh with and be operated by a stationary rack 6 secured to one side of the window frame in a manner hereinafter more fully described.

A bifurcated lever 7 is pivotally secured as at 8 to the bracket 2 having the horizontal slot 3 therein, said lever bein also provided with a pin 9 which is adapted apertures 10 and 12 in the said bracket 2. When the pin 9 is in the aperture 10 the lever 7 is secured in the position indicated in Fig. 3, which retains the pinion 5 of the roller 4;, which is rotatably mounted within 1- the upper bifurcated portion of the said lever 7, in mesh with the rack 6. The lever 7 may be constructed of spring steel or a similar material so as to impart resiliency thereto and thus retain the pin 9 in either aperture 10 or 12. By moving the lever 7 to the position indicated in Fig. 4 of the drawings, the pinion 5 is disengaged from the stationary rack 6.

The upper end of the screen 14-. is bent as at 15 around one legof an angle 16 and securely clamped thereon by means of the U.-

to engage the Q I Lil-spat shaped member 17', as illustrated'inexaggerated form in Fig. 6 of the drawings. The U-shaped member 17 is then inserted and secured within the longitudinal slot 4 of the roller 4, in this manner the upper end of the screen 14 is secured to the roller. The lower end of. the screen 14 is overlapped and secured by means of a binding strip 18 which is in turn secured by meansv of-the securing strip 19. 1

Vertical stationary retainin strlps 22 and 23 are secured to the sides o the beads 25 of the window frame, the strips 22 being provided with a channel 24-'adapt'edto receive' the rack 6. The securing strip 19 secured to the window sill 30 by means of the pivotal buttons 27"whiclr, extend through the slots 29 of the strip 19 are turned transversely tothe said slots.

The operation is as follows. The roller 4 being rotatably mounted to the lower end of the sash land the lower end of the screen 14 being secured, by means of the buttons 27 and securing strip 19, to the Window $111 30, as the lower'sash 1 is raised it causes the roller 4 and the pinion 5 thereon to move with the said sash '1 and the pinion 5 to roll on the rack 6 and unwind the screen 14 and the pinion 5 is rotated in the opposite "direction by the rack 6 and the screen 14 is,

consequently, rolled upon the roller 4. If

it is desired to raise thewindow without operating the screen 14, the pinion 5 is disengaged from the rack 6 by moving the pin 9 of the lever 7 into the'aperture 12 as. indicated in Fig. 4 of the drawings. The securing strip 19 may bereleased from the window sill 30 by turning the buttons 27 so that they will coincide with the slots .29. The window sash l'may now be raised or a lowered without unwinding or winding the screen 14, the said screen being rolled on the roller 4 and raised or lowered with the said sash 1.

In Figs. 7, 8 and!) ofthe drawings, I have illustrated a modified form of the invention wherein the roller 4 is rotatably mounted between the slides of the window frame and the rack 6 is slidabl mounted 1 within the channel 24- of onefo the screenguides 32.

' The lower end of the rack 6: isnr1gidly 'secured to the securing strip .19. The guides 32 are in the form of deep channels, are stationary and extend from the roller 4 "to the'window sill 30. I By releasing the secur v ing strip 19 from'the buttons 27 and raising the said securing strip, therackt-will also be raised and will thereby'rotate the pinion 5 01E the roller 4and wind the screen 14 there'- on. The guide strips 32 will engage and re- 'tain the edges of the screen 14 and efiectively prevent the. entrance of .fiies -or other insects. Byreversing the movement. and

lowering the securing strip 19 the rack 6 will also be lowered and rotate the pinion 5 and the roller 4'in the opposite direction. The screen 14 will then be unwound from the roller 4 as the securing strip 19 moves downward. When the. securing strip 19 the rack or the pinion may be stationary.

It is also obvious thatthe window screen may be operated automatically by raising or lowering the window sash, or may be disconnected from the sash and operated in dependently.

Having thus described my invention what I claim as new, and desire to secure by Letters Patent is- 1. in a rolling window screen, the comblnation of suitable bracketsadapted to be secured to the lower end of a window sash;
